Electronic address:

Background: Appetite-regulating hormones are implicated in anorexia nervosa (AN) pathophysiology, however, data are limited for appetite-regulating hormones across the AN weight spectrum. We aimed to investigate fasting and post-prandial concentrations of appetite-regulating hormones - peptide YY (PYY), cholecystokinin (CCK), and ghrelin - among adolescent and young adult females across the AN weight spectrum, specifically those with AN and Atypical AN, and healthy controls (HC).

Methods: Participants (N = 95; ages 11-22 years) included 33 with AN, 25 with Atypical AN, and 37 HC.

Introduction: Limited health literacy - the ability to access, process, and use health information and services - contributes to persistent health inequities. Yet little is known about associations of limited health literacy with impacts from the COVID-19 pandemic, particularly for US adults in rural areas. This study sought to determine associations of limited health literacy with impacts from the COVID-19 pandemic among a diverse sample of adults in rural Northern Arizona.

Objectives: Career duration is often used as a metric of neurotrauma exposure in studies of elite athletes. However, as a proxy metric, career length may not accurately represent causal factors, and associations with health outcomes may be susceptible to selection effects. To date, relationships between professional American-style football (ASF) career length and postcareer health remain incompletely characterised.

Background: The role of tyrosine kinase inhibitors (TKIs) in early-stage and metastatic oncogene-driven non-small cell lung cancer (NSCLC) is established, but it remains unknown how best to integrate TKIs with concurrent chemoradiotherapy (cCRT) in locally advanced disease. The phase 2 ASCENT trial assessed the efficacy and safety of afatinib and cCRT with or without surgery in locally advanced epidermal growth factor receptor (EGFR)-mutant NSCLC.

Patients And Methods: Adults ≥18 years with histologically confirmed stage III (AJCC 7th edition) NSCLC with activating EGFR mutations were enrolled at Mass General and Dana-Farber/Brigham Cancer Centers, Boston, Massachusetts.

Ann Romney Center for Neurologic Diseases, Brigham and Women's Hospital, Boston, MA, United States; Department of Neurology, Harvard Medical School, Boston, MA, United States; Brigham Multiple Sclerosis Center, Department of Neurology, Brigham and Women's Hospital, Boston, MA, United States.

Article Synopsis
  • The study investigates how well the Patient Reported Outcome Measurement Information System Scale v1.1-Global Health (PROMIS-10) correlates with longer PRO measures like SF-36 and Neuro-QoL in patients with multiple sclerosis (MS).
  • Strong correlations were found between PROMIS-10 and SF-36 domains, indicating effective measurement of similar constructs, especially in physical and mental health components.
  • PROMIS-10 scores also showed a stronger relationship with physical disability status (EDSS) compared to mental health, suggesting physical health impacts are more notable in MS patients.

Article Synopsis
  • The study investigates how combat exposure affects behavioral outcomes, specifically focusing on alcohol-related behaviors and subjective well-being, using a large data set from UK BioBank.
  • Researchers created hypothetical experiments to compare individuals with combat exposure versus those without, adjusting for relevant factors.
  • Findings indicate that combat exposure is linked to negative effects, such as increased daily alcohol consumption and decreased general happiness, contributing to a better understanding of these issues in psychological science.

Association Between Metabolic Syndrome Inflammatory Biomarkers and COVID-19 Severity.

J Endocr Soc

March 2023

Section of Pulmonary Diseases, Critical Care and Environmental Medicine, John W. Deming Department of Medicine, Tulane University School of Medicine, New Orleans, LA 70112, USA.

Context: Metabolic syndrome (MetS) is associated with increased risk of severe COVID-19. MetS inflammatory biomarkers share similarities with those of COVID-19, yet this association is poorly explored.

Objective: Biomarkers of COVID-19 patients with and without MetS, the combination of diabetes, hypertension, obesity, and/or dyslipidemia, were analyzed to identify biological predictors of COVID-19 severity.

Neuropathology-Independent Association Between Genotype and Cognitive Decline Rate in the Normal Aging-Early Alzheimer Continuum.

February 2023

University of Massachusetts School of Public Health & Health Sciences (J.Q., Y.Z.), Amherst; Massachusetts General Hospital Biostatistics Center (J.Q.), Boston; New York University School of Global Public Health (R.A.B.); New York University Alzheimer's Disease Research Center (R.A.B.); Massachusetts General Hospital Neurology Department (B.T.H., A.S.-P.), Boston; Massachusetts Alzheimer's Disease Research Center (B.T.H., A.S.-P.), Charlestown; and Harvard Medical School (B.T.H., A.S.-P.), Boston, MA.

Background And Objectives: We previously found that the genotype affects the rate of cognitive decline in mild-to-moderate Alzheimer disease (AD) dementia independently of its effects on AD neuropathologic changes (ADNC) and copathologies. In this study, we tested the hypothesis that the alleles differentially affect the rate of cognitive decline at the normal aging-early AD continuum and that this association is independent of their effects on classical ADNC and copathologies.

Methods: We analyzed associations with the cognitive trajectories (Clinical Dementia Rating scale Sum of Boxes [CDR-SOB] and Mini-Mental State Examination [MMSE]) of more than 1,000 individuals from a national clinicopathologic sample who had either no, mild (sparse neuritic plaques and the Braak neurofibrillary tangle [NFT] stage I/II), or intermediate (moderate neuritic plaques and the Braak NFT stage III/IV) ADNC levels at autopsy via 2 latent classes reverse-time longitudinal modeling.

Objective: To examine the relationships between age, healthspan and chronic illness among former professional American-style football (ASF) players.

Methods: We compared age-specific race-standardised and body mass index-standardised prevalence ratios of arthritis, dementia/Alzheimer's disease, hypertension and diabetes among early adult and middle-aged (range 25-59 years) male former professional ASF players (n=2864) with a comparator cohort from the National Health and Nutrition Examination Survey and National Health Interview Survey, two representative samples of the US general population. Age was stratified into 25-29, 30-39, 40-49 and 50-59 years.

Introduction: Clinical investigators often seek to identify biomarkers that are associated with clinical outcomes. The challenge is that biomarkers tend to be numerous, often inter-correlated, and with varying degrees of association with the clinical outcome of interest. We developed a straightforward, effective visualization approach that allows investigators to see the inter-correlations of biomarkers and their association with clinical outcomes rendered in a 2-dimensional (2-D) plot.

Bone metastases are often difficult to manage as they can be symptomatic and skeletal-related events (SREs) can contribute to significant morbidity and declines in performance status. We sought to identify a novel medical treatment for bone metastasis by testing the safety and efficacy of cabozantinib in patients with bone metastasis arising from non-breast, non-prostate, malignant solid tumors. Patients were administered cabozantinib as an oral drug starting at 60 mg per day and radiologic measurements were performed at baseline and every 8 weeks.

Objective: Numerous adverse prenatal exposures have been individually associated with risk for psychiatric illness in the offspring. However, such exposures frequently co-occur, raising questions about their cumulative impact. We evaluated effects of cumulative adverse prenatal exposure burden on psychopathology risk in school-aged children.
